Deep patch embankment repair with geosynthetics (DPERG) is a cost-effective and sustainable method of mitigating roadway embankment damage associated with shallow slumping of the outside shoulder. DPERG is a shallow embankment repair that consists of subexcavating 3 to 6 ft (1 to 2 m) and backfilling with granular material and layers of geosynthetic reinforcement that are vertically spaced 6 to 24 in. (150 to 600 mm). DPERG is constructed either half width or full width, depending on the extent of roadway distress. Use of the deep patch on federally owned roads in the Pacific Northwest dates back to the 1980s. Recent research has improved understanding of soil–geosynthetic interaction, and this knowledge has led to improved DPERG performance and a reduction in DPERG costs. This paper summarizes design and construction recommendations gained from this recent research and experiences with hundreds of DPERGs constructed on Western Federal Lands Highway Division projects in the Pacific Northwest.
